[GIT pull] smp/hotplug fix for 4.10

[Thomas Gleixner]

Linus,

please pull the latest smp-urgent-for-linus git tree from:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git 
smp-urgent-for-linus

Remove an unused variable which is a leftover from the notifier removal.

Thanks,

        tglx
